As for the original question, I think if the Patriots win it would push the markets up just a little bit. I can't stand the Pats and hope they lose, but they have come to reperesent America overall, and people love to see a perfect season. They have a huge fanbase, and if they win, their fans will feel good about themselves and presumably spend more.

I heard on CNBC the other day that 81% of the time that if the NFC team wins, the market finishes higher that year and if the AFC team wins, the market finishes lower.

I think this correlation is probably due to the fact that during the 70's when the AFC was dominating the NFL, was a horrible time for the market. And conversely, in the 80's/90's when the NFC was typically winning the SuperBowl, the markets were doing very well overall.

Here is a correlation. If you are a fun of either team, do not trade tomorrow. Why? It is likely that you may not feel very good or you will feel invincible after the game--- either way, this sentiment is a good fuel for the market to consum!
